Adex Announces NI 43-101 Compliant "Indicated" Mineral Resource Estimate of 10.88 Million Tonnes for the North Zone's Tin-Indium

Adex Mining Inc. ("Adex" or the "Company") (TSX VENTURE:ADE) is pleased to
announce that it has completed a National Instrument 43-101 ("NI 43-101")
compliant Mineral Resource estimate for seven tin-indium-zinc (Sn-In-Zn)
sub-(zones and one tungsten-molybdenum-bismuth (WO3-MoS2-Bi) sub-zone which make
up) the North Zone ("NZ") at its wholly-owned Mount Pleasant Mine Property in
southwestern New Brunswick, Canada ("Mount Pleasant" or the "Property"). The
total Sn-In-Zn resource estimate includes an Indicated Mineral Resource of
10,882,000 tonnes, plus an Inferred Mineral Resource of 7,603,000 tonnes.


The NI 43-101 compliant Mineral Resource estimate for the NZ indicates the
opportunity for both near surface and at depth mineralization. This will have
implications for further studies when assessing the economic potential of
developing a near surface, open pit and/or underground mining operation at the
NZ.


The NI 43-101 compliant Mineral Resource estimate, completed by Watts, Griffis
and McOuat Limited ("WGM") using an updated GEMCOM model, was completed in
conjunction with the preparation by WGM of an independent NI 43-101 Technical
Report under the supervision of Trevor Boyd, P.Geo., the Company's Geological
Consultant.


Details of the NI 43-101 compliant mineral resource estimate are as follows.

The resource estimate for the Sn-In-Zn sub-zones was based on a cut-off grade of
0.25% Sn equivalent (Sn eqv.), equal to % Sn + 41.67 x % In. The 0.25% Sn
equivalent cut-off grade was provided by Adex based on a value of the
mineralized material of US$30/tonne derived from the previous six-year price
trend and price relationship between tin and indium using an estimated tin price
of US$12.0/kg and indium price of $500/kg. Zinc was not incorporated into the
estimation of the cut-off grade. In consultation with WGM and based upon these
metal prices, Adex has determined that 0.25% Sn equivalent is an acceptable
cut-off grade to report the resources.


Until an economic evaluation is completed, the economic cut-off for this deposit
is unknown. Mineral resources that are not mineral reserves do not have
demonstrated economic viability.


A policy of capping of high indium grades was implemented based upon the
statistical distribution of the metal within each individual sub-zone. Hence the
Upper Deep Tin, Deep Tin, #5 Tin Lode, #1-3 Tin Lode, Endogranitic and North
W-Mo sub-zones had capped indium grades at 965, 830, 750, 500, 200 and 200 g/t,
respectively. No capping of indium was required for the North Adit or the #4 Tin
lode.


If a cut-off grade of 0.30% WO3 equivalent is applied to the estimate of the
North W-Mo sub-zone then the Inferred Resource is estimated to be 3,278,800
tonnes grading 0.10 % Sn, 23.5 g/t In (21.9 g/t In capped) 0.27 % Zn, 1.02 % As,
0.27 % WO3, 0.16 % MoS2, 0.05 % Cu, and 0.14 % Bi. The cut-off grade of 0.30%
WO3 equivalent, equal to % WO3 + 1.5 x % MoS2, was provided by Adex. This was
based on a value of the mineralized material of US$30/tonne at a tungsten price
of US$100/MTU (US$10.0/kg WO3) similar) to that used for the NI 43-101 resource
estimation and technical report for the Fire Tower Zone (the "FTZ") at the
Property. The technical report on the FTZ (the "FTZ Technical Report") entitled
"A Technical Review of the Mount Pleasant Property, Including an updated Mineral
Resource Estimate on the Fire Tower Zone, Southwestern New Brunswick for ADEX
Mining Inc." dated December 1, 2008 and completed by Paul Dunbar, M.Sc., P.Geo.
Senior Associate Geologist of Watts, Griffis and McOuat Limited, Dorota A.
El-Rassi, M.Sc., P.Eng., Geological Engineer of SRK Consulting and John S.
Rogers, P.Eng., of Aker Metals, a division of Aker Solutions Canada Inc., is
available on www.SEDAR.com.


The boundaries of the mineralized body were interpreted manually by Trevor Boyd,
P.Geo., the Company's Geological Consultant. Mineralized zones were commonly
cross-cutting geological units and structural boundaries. Consequently, resource
boundaries were defined based solely on % Sn and % In values (or % WO3 and %
MoS2 values in the case of the North W-Mo sub-zone). These were plotted on cross
sections spaced 25 metres apart and mineralization boundaries were drawn halfway
between drill holes. If no holes existed to limit the mineralization outlines,
the boundaries were extended to a maximum of 20 metres away from the nearest
hole. In general, extensions of the boundaries were made consistent with the
trends defined by joining known cut-off boundaries. A minimum width of 3 metres
was used for defining the zones, and a specific gravity of 2.70 was used for
estimating the resources.


The eight modeled sub-zones that make up the North Zone are distributed over an
area of 450 by 250 metres extending from the surface to a vertical depth of 450
metres. They are located 800 metres north of the WO3 - MoS2 FTZ for which an NI
43-101 compliant Indicated Resource of 13,489,000 tonnes, plus an Inferred
Resource of 841,700 tonnes, was reported in FTZ Technical Report.


The #4 Tin Lode and #5 Tin Lode sub-zones extend from the surface to a vertical
depth of 70 metres. The #1-3 Tin Lode sub-zone extends from the surface to a
vertical depth of 160 metres. The Upper Deep Tin sub-zone is situated beneath
the #5 Tin Lode extending from 80 to 160 metres vertical depth. The Deep Tin
sub-zone reaches to within 40 metres laterally of the Upper Deep Tin Zone
extending from 140 to 270 metres vertical depth. The North Adit sub-zone
consists of four mineralized regions distributed from the surface to a vertical
depth of 250 metres. The North W-Mo sub-zone consists of three mineralized
regions extending from 80 to 350 metres vertical depth. The Endogranitic
sub-zone extends from 250 to 450 metres vertical depth. An 1,100 metre decline,
which was used to collect bulk samples in 1986, extends from the Fire Tower Zone
underground workings to the Endogranitic sub-zone. The decline and underground
workings are presently flooded. An exploration drive developed in the 1960s
extends from the surface to the vicinity of the #4 Tin Lode and the #1-3 Tin
Lode sub-zones. The condition of the drive is presently unknown.


The mineral resources are reported in accordance with NI 43-101 and the Canadian
Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards,
November 2004 and have been estimated in conformity with the CIM Estimation of
Mineral Resource and Mineral Reserves Best Practices Guidelines, November 2003.
The Company has implemented an industry standard quality control program on its
drill core and assaying since the inception of its drilling program.


Paul Dunbar, M.Sc., P.Geo., Senior Associate Geologist of WGM, an independent
qualified person as defined by National Instrument 43-101, carried out site
visits to the Property in May and June, 2008 during which he examined the
drilling program and core, and completed check sampling and assaying of core
samples. Robert de l'Etoile, P.Eng., Geological Engineer and consultant to WGM,
an independent qualified person as defined by National Instrument 43-101,
checked assay results against the GEMCOM database. The database verification
found no significant discrepancies in the geological information, which
conformed to industry standards. Pulp duplicates of the drill core samples,
unknown to the laboratory, were sent to a second laboratory fulfilling standard
QA/QC protocols. Analytical results for some of these samples remain pending.


None of Trevor Boyd, the Company's Geological Consultant, Paul Dunbar, Robert de
l'Etoile or Management of the Company is aware of any known environmental,
permitting, legal, title, taxation, socio-political, marketing or other relevant
issues that may materially affect the estimate of the mineral resource.


Trevor Boyd, P.Geo., the Company's Geological Consultant, supervised the
preparation of the mineral resource estimate for the North Zone and the
technical information contained in this press release in compliance with NI
43-101. Paul Dunbar is preparing the NI 43-101 Technical Report on the North
Zone, which Adex will file on SEDAR within 45 days of today's date.

Report.
